Screw Anchors

Concrete screw anchors are threaded mechanical fasteners designed for use in concrete, brick, and block. As the anchor is driven into a properly drilled hole, the threads cut into the base material to create a secure hold. This makes concrete anchor screws a practical option for applications that need strong holding power, straightforward installation, and the ability to remove or replace the fastener when needed.

Tanner Bolt supplies concrete screw anchors in a wide range of diameters, lengths, head styles, and materials to fit both light-duty and heavy-duty fastening jobs. Use them for securing fixtures, brackets, rails, framing components, electrical attachments, and other assemblies in masonry materials.

When choosing screw anchors for concrete, consider the base material, load requirements, embedment depth, head style, and exposure conditions. Carbon steel anchors are commonly used for general-purpose interior applications, while stainless steel concrete screw anchors are better suited for corrosive or moisture-prone environments. Flat head styles are useful where a flush finish is important, while hex washer and other drive styles can be easier to install in general construction settings.
